On Wednesday, first-generation FuelBand devices popped up on the online clearinghouses Gilt and The Clymb, both selling for $79, or 47% off the retail price of $149. Both were part of so-called flash sales, in which the product is available for purchase for a day or two, according to the websites.

The sales come after Nike last month confirmed there would be layoffs in the department that makes FuelBand devices, “as our Digital Sport priorities evolve.” The sportswear maker did reiterate its commitment to growing the user base for its so-called “Nike +” software and fitness apps, and said it would continue to sell the latest edition FuelBand SE “for the forseeable future.”

Nike spokesman Reggie Borges said that the company has decided to expand it’s distribution channels for its first generation FuelBand devices.

Jennifer Miller, a spokeswoman for Gilt, said the luxury-goods site doesn’t disclose the quantity of how many units it has available. The FuelBand offering began at noon on Wednesday and will last through the weekend, she said.

According to its website, The Clymb offers outdoor gear and travel packages at competitive prices, and its FuelBand sale is expected to last for at least two days.

Corrections & Amplifications - The first generation Nike FuelBand flash sale on Gilt will last through the weekend. A previous version of this article incorrectly said the sale would last 36 hours.
